Add batching mechanism to reduce checkpoint frequency and improve execution performance by grouping multiple checkpoint operations before persisting state changes. - Add batch size configuration to control checkpoint frequency - Implement batching logic in state management layer - Update execution flow to support deferred checkpointing - Asynchronous checkpoints (is_sync=False, batched for performance): - Step START with AtLeastOncePerRetry semantics - Child context START operations - Wait for condition START operations - Synchronous checkpoints (is_sync=True, immediate persistence): - Step START with AtMostOncePerRetry semantics - Operation completion (SUCCEED/FAIL) - Callback START operations - Invoke START operations - Large result checkpoints - Add batch flush on critical operations and execution completion - Implement parent-child tracking and orphan detection for parallel operations - Maintain backward compatibility with existing checkpoint behavior - Ensure state consistency across batch boundaries
